Definitions
- the nerve injuries or nervous system injuries are caused by a change in the ion flux into neurons or a nervous system tissue.
- nervous system tissue refers to animal tissue comprising nerve cells, the neuropil, glia, neural inflammatory cells, and endothelial cells in contact with “ nervous system tissue”.
- Nevous system tissue refers to animal tissue comprising nerve cells, the neuropil, glia, neural inflammatory cells, and endothelial cells in contact with " nervous system tissue”.
- Neve cells may be any type of nerve cell known to those of skill in the art including, but not limited to neurons.
- neuroon represents a cell of ectodermal embryonic origin derived from any part of the nervous system of an animal.
- the strength of inhibition for a selective inhibitor may be described by an inhibitor concentration at which inhibition occurs (e.g., an IC50 (inhibitor concentration that produces 50% of maximal inhibition) or a Ki value (inhibition constant or dissociation constant)) relative to different ASIC family members.
- An ASIC1a-selective inhibitor may inhibit ASIC1a activity at a concentration that is at least about two-, four-, or ten-fold lower (one-half, one-fourth, or one-tenth the concentration or lower) than for inhibition of at least one other or of every other ASIC family member.
- the proper fluidity can be maintained, for example, by the use of a coating such as lecithin, by the maintenance of the requited particle size in the case of dispersion and by the use of surfactants.
- Prevention of the action of microorganisms can be achieved by various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol, ascorbic acid, thimerosal, and the like.
- isotonic agents for example, sugars, polyalcohols such as manitol, sorbitol, sodium chloride in the composition.
- Prolonged absorption of the injectable compositions can be brought about by including in the composition an agent which delays absorption, for example, aluminum monostearate and gelatin.
- FIG. 7A shows exemplary 340/380 nm ratios as a function of pH, illustrating an increase of [Ca 2+ ] i by pH drop to 6.0.
- the amiloride analogs may contain a water solubilizing group, such as an N,N-dimethyl amino group or a sugar, at the guanidino group to improve water solubility.
- the amiloride analogs may have a water solubility of 5 mM, 10 mM, 20 mM, 30 mM, 40 mM, 50 mM, 60 mM, 70 mM, 80 mM, 90 mM, 100 mM or higher.
- the amiloride analogs may have a solubility that allows for a 10 mg, 25 mg, 50 mg, 100 mg, 150 mg, 200 mg, 250 mg, 300 mg, 400 mg, or 500 mg dose to be administered intravenously to a human in a single 10 ml injection.
